Brains of one-handed people suggest new organization theoryIn people born with one hand, the brain region that would normally light up with that missing hand’s activity lights up instead with the activity of other body parts — including the arm, foot, and mouth — that fill in for the hand’s lost function. Now, researchers say that the discovery could shake up scientists’ fundamental understanding of how the brain is organized.In people born with one hand, the brain region that would normally light up with that missing hand’s activity lights up instead with the activity of other body parts — including the arm, foot, and mouth — that fill in for the hand’s lost function.
